VAPOR-BURNING STOVE.

SPECIFICATION forming part of Letters Patent No. 410,537, dated September 3, 1889.

Application filed May 13, 1889. Serial No. 810,675. (No model.)

To aZZ whom it may concern.-

Be it known that I, JESSE ll. CURL, a citizen of the United States of America, and a resident of Des Moines, in the county of Polk and State of Iowa, have invented an improved Vapor Generator and Burner, of which the following is a specification.

My object is to provide a 'apor-burning attachment that is adapted to be applied to stoves of common form in such a manner that it can be readily operated, with economy and safety, by any person of ordinary intelligence for the purpose of cooking and all the common uses of a stove.

My invention consists in the construction and combination of a vapor-generator and one or more vapor-burners with a stove, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure l is a top view of my vapor-generator from which the top side or cover is removed. Fig. 2 is a vertical sectional view through the longitudinal center of the vaporgenrator, as indicated by the dotted line in Fig. 1. Fig. 3 represents a section of one of my burners that has been divided at its vertical center. Fig. l shows my complete invention applied to a stove as required for practical use. Fig. 5 is a top view showing two burners combined in such a manner that the burners can be operated independently whenever desired. Fig. 0 is a side view of the same two burners and the tubes that connect them and a solid deflector that projects over the tops of the burners. Fig. 7 is a sectional view of the tube and burner connecting device, located midway between the two burners in Fig. 6.

a and Z) are the flat parallel walls and top and bottom of my oil-receptacle and vaporgenerator cast complete in one piece. It may vary in depth and length, as desired. Its end portions are preferably circular in shape and broader than the central portion and terminate in tubular screw-threaded socketsc, adapted to receive a plug (I at one end and the tube f at the other end, to be thereby connected with an elevated reservoir in a common way.

g is an integral elbowshaped partition in the interior that extends from the center por tion to near one end in such a manner that oil introduced through the tube f at one end will flow to the other end to pass around the end of the partition, and then backward to an opening 71. in the central portion of the bottom 1).

m is a screw-threaded socket extending outward to receive the end of atube.

n is the main portion of my burner, made of iron by casting in a mold. It has an open flaring top a and parallel integral open-ended tubes a, that extend downward from its sides to convey air to the combustion-chamber at their open top ends.

11 is an integral tube in a horizontal position, that has one end open and screwthreaded, and adapted to receive the end of a tuber. A perforation in the top of the tube n' allows oil and vapor to escape into the combustion-ehamber and perforations in the bottom of the combustion-chamber, and on the opposite sides of the horizontal tube allow oil to escape and to drop down upon an absorbent material, where it can be set on fire to start the generation of vapor in the burner, and also in the generator above the burner, by means of a Tcoupling, as shown in Fig. 4:, in such a manner that oil and vapor can be thereby conveyed and distributed to the burners. 8 in Fig. 4c is a tube connected with the T-coupling and the vapor-generator, as re quired to support the generator.

In place of the T-coupling the device shown in Figs. 5, 6, and 7 may be advantageously substituted. It is tubular and has two distinct chambers s and s, so that separate tubes may be connected therewith and each burner operated independently of the other whenever desired. l

s is an integral vertical projection adapted to support a solid plate a in place of the vaper-generator. A stud on the top of the pro j ection enters a corresponding perforation in the center of the plate and detachably con nects the two parts. \Vhen the plate is used in place of the vapor-generator, the heat generated by the burners will be deflected and distributed by the plate, and the chambers s will serve as vapor-generators.

y represents a metal plate fitted in a stove and supported above the grate. It has openings through which the air-conveying tubes n of the burner extend downward. Lugs or projections on the tubes, as indicated by dotted lines in Fig. 3, will engage the plate and retain the burners and generator combined at a proper elevation Within the stove, as required to utilize the heat generated by the burners, where pots and kettles can be placed in and over the openings in the top plate of the stove.

5 (shown in Fig. 4) represents a check-valve connected with the tube f to arrest the flow of oil from a reservoir at the top of the tube.

To start a fire as required in the practical use of my invention thus combined with a stove, it is only necessary to open the valve to allow oil to flow through the generator and the burner to drip upon the plate y in the stove, or upon asbestus or other suitable material placed upon the plate and around the the tubes 02', so that it can be lighted with a match. As soon as the burning oil heats the burners and generator, the oil therein will be converted into vapor and the vapor will burn at the tops of the burners and continue to produce vapor in the generator at the same time that the heat is utilized at the top of the stove for cooking.

To stop the operation, it is only necessary to close the valve in the tube f to arrest the flow of oil.

I am aware vapor-burners have had openings in their bottoms to admit air; but my manner of forming a burner complete in one piece and combining it with a generator and a deflector and a stove is novel and greatly advantageous.

I am also aware that burners have been cast complete in one piece; but my peculiar form of burner and my manner of combining two burners with a coupling device and deflector and a perforated plate in a stove are novel and greatly advantageous in converting a cook-stove that has a grate for burning coal into a vapor-burning stove.

I claim as my invention 1. A vapor-burner cast complete in one piece, comprising a hollow metal case or combustion-chamber having a contracted neck and flaring open top at its center, open-ended tubes at its out-side extending downward, an integral tube extending across the bottom and open at one end to be connected with an extraneous tube, a perforation in the top of said horizontal tube, and one or more perforations in the bottom of the case at the side of said horizontal tube, substantially as and for the purposes stated.

2. A vapor generator and burner coupling device cast complete in one piece and provided with two distinct chambers and two openings in each chamber to admit tubes, and an integral post adapted to support a deflector, in combination with two burners and a deflector, for the purposes stated.

3. The combination of a generator having a post adapted to support adeflector, two burners and tubes extending therefrom into distinct chambers in the generator, and a deflector extending horizontally over the tops of the burners, in the manner set forth, for the purposes stated.

4. The vapor-burners 41, having open tops 41, open-ended tubes n, and perforated tubes n, a generator 8, having chambers s and s, and an integral post s ,a deflector on said post extending horizontally over said burners,

arranged and combined substantially as shown and described, for the purposes stated.

5. A burner 02, having tubes n", a plate 3 having perforations to admit said tubes, a

vapor-generator, and flame-deflector arranged and combined with a stove, in the manner set fortl1,for the purposes stated.
